I bought some intellivision games today and these were in the box. I thought they were just games taken out of the shell, but the person I bought them from said they haven't been touched in years. He said his at her brought them home from work when he worked for Mattel. One is obviously a test cartridge, but I've never seen one like it. I have no clue what the other three are because I do not currently have a system. I was hoping someone would know what they are. I know it's a longshot, but if anyone knows, it'll be the folks here.
Thanks for any help!
